RESUMO
BACKGROUND: Maternal cytomegalovirus (CMV) and rubella infections have adverse neonatal outcomes. Basic epidemiological data concerning CMV and rubella is necessary for health planners and care providers. METHODS: A cross sectional study was conducted at El-Rahad hospital, Sudan to investigate seroprevalence of CMV and rubella infections and associated possible risk factors among pregnant women. Structured questionnaires were used to gather socio-demographic data and ELISA was used to detect CMV and rubella infections using IgG and IgM. RESULTS: Out of 231 pregnant women, 167 (72.2%) and 151 (65.3%) were CMV-IgG and rubella-IgG positive, respectively. Only 6 (2.5%) and 8 women (3.4%) were CMV-IgM and rubella-IgM positive, respectively. While, high parity (OR = 14.7, 95%CI = 1.7 - 123.6; P = 0.01] and illiteracy (OR = 3.0, CI = 1.4 - 6.5; P = 0.004) were significantly associated with seropostive CMV-IgG in multivariate analysis, none of the other obstetrical and medical characteristics were significantly associated with CMV or rubella infections. CONCLUSION: CMV prevalence was 72.2% and rubella susceptibility among pregnant women was 34.6%. Rubella vaccine and routine screening for rubella and CMV should be introduced for pregnant women in this setting. Further research is needed.

Diabetic retinopathy is the most common complications of diabetes mellitus that, in most occasions, lead to blindness. Multiple evidences linked the serum magnesium, iron and ferritin disturbance with diabetes and its complications. A case-control study was conducted at Makkah Eye Complex, Khartoum, Sudan, to compare the levels of serum magnesium, iron and ferritin in patients with diabetic retinopathy with diabetic patients without diabetic retinopathy (controls). Findings indicate that all patients had type 2 diabetes. The two groups (50 in each arm) were well matched in their basic characteristics. Median (25th-75th interquartile) of serum magnesium in patients with diabetic retinopathy were significantly lower than patients without diabetic retinopathy [1.48 (0.75-1.64) vs. 1.92 (1.4-2.3)mg/dl, P = 0.022]. The median of serum iron and ferritin were lower in cases than control group but did not reach a statistical significance [20.5 (17.2-48.0) vs. 27.0 (16.0-54.0) µg/dl, P = 0.568; 98.0 (45.0-134.75) vs. 101.0 (47.0-161.0) µg/l, P = 0.818]. The duration of diabetes [16.5 (9.3) vs. 11.2 (6.6) years; P = 0.014] and haemoglobin level [13.7 (0.9) vs. 12.5 (2.0) g/dl; P = 0.039] were significantly higher in cases group than control group. A significant inverse correlation was observed between serum magnesium and iron levels. Twenty (40 %) patients had severe non-proliferative diabetic retinopathy with mild macular edema, which is the most prevalent type among the cases group. Hypomagnesaemia among diabetic patients was associated with diabetic retinopathy, while serum iron and ferritin have no significant effect in this setting. Severe non-proliferative diabetic retinopathy with mild macular edema is the prevalent type in this study.
